This standard specifies methods for uniform assessment and the recording of:
-- the A-weighted sound power level;
-- the sound power spectrum;
-- a calculation method for an overall average sound pressure level at a given distance.
Among these data, the sound power level is the only unambiguous characteristic.
This standard is applicable to:
-- forced convection air cooled refrigerant condensers as specified in EN 327;
-- air cooled liquid coolers "dry coolers" as specified in EN 1048.
